i get this violent shake from the engine and i was wondering how i can fix this?? From my knowledge, im thinking it could be an airflow issue. If not, could someone help me out please, thanks.

Also, i want to change my stock interior lighting for the instrumental planel and the dashboard area to a different color, and i was wondering where or how i can do it without those tacky neon lights that stick onto the dash or other areas.

 

Maybe if you describe when the violent shake happens or the conditions under which it happens we can actually help you diagnose it.

As for the lighting, LED's. Many have done this.

 

The violent shake only occurs when i go from a red light or from a sudden stop. And as for the led lights, where i can get them?
